Le secteur Open Source connaît une profonde mutation: à côté de l’idéologie libertaire prônée par ses défenseurs, il migre vers une "économie de marché" au sein de laquelle les acteurs développent désormais de réelles stratégies commerciales. A partir d’une étude exploratoire, basée sur l’analyse de six cas d’entreprises, notre recherche met en évidence les modèles d'affaires privilégiés par ces sociétés pour positionner leur offre de produits/services et générer un retour lucratif à leurs activités. Synthétisés au travers de trois approches distinctes – les logiques de la complexification, du système clos et de l’intermédiation –, ces modèles économiques reflètent des positionnements foncièrement différents par rapport à la philosophie Open Source et soulignent les ressources (au sens de Barney, 1991) que les entreprises mobilisent pour créer un lien de dépendance envers leur clientèle et se forger un avantage concurrentiel durable.

Biofilms are well recognised in different settings. Endodontic biofilms containing bacteria responsible for bacteraemia and secondary infection of total hip arthroplasties (THA) represent a diagnostic challenge because they are often asymptomatic. Their treatment is difficult and inadequate management of such unrecognised sources of systemic infection can lead to the devastating situation of an infected arthroplasty necessitating implant removal, long term antibiotic treatment and secondary implantation of a new prosthesis. Since about ten percent of secondary infected THA can have a dental origin, this article is intended to give guidelines to all intervening care providers: general practitioner, orthopaedic surgeon and dentist.

Falls are frequent in the elderly and are responsible for an increased morbi-mortality. The elderly who has a tendency to fall is at higher risk of repeated hospitalisation and of institutionalisation. A link between cognitive and gait disorders is put forward by several recent studies. This paper is concerned with the various gait abnormalities encountered in the elderly, especially seriale gait, and the means to detect them. [less ▲]

Granule neurons of the dentate gyrus (DG) of the hippocampus undergo continuous renewal throughout life. Among cell cycle regulators, cyclin-dependent kinase 2 (Cdk2) is considered as a major regulator of S-phase entry. We used Cdk2-deficient mice to decipher the requirement of Cdk2 for the generation of new neurons in the adult hippocampus. The quantification of cell cycle markers first revealed that the lack of Cdk2 activity does not influence spontaneous or seizure-induced proliferation of neural progenitor cells (NPC) in the adult DG. Using bromodeoxyuridine incorporation assays, we showed that the number of mature newborn granule neurons generated de novo was similar in both wild-type (WT) and Cdk2-deficient adult mice. Moreover, the apparent lack of cell output reduction in Cdk2(-/-) mice DG did not result from a reduction in apoptosis of newborn granule cells as analyzed by TUNEL assays. Our results therefore suggest that Cdk2 is dispensable for NPC proliferation, differentiation and survival of adult-born DG granule neurons in vivo. These data emphasize that functional redundancies between Cdks also occur in the adult brain at the level of neural progenitor cell cycle regulation during hippocampal neurogenesis. [less ▲]

The borderline personality disorder is a common psychiatric entity, which is characterized by a varied symptomatology and a significant comorbidity. It seems that its etiologic is heterogeneous, comprising psychosocial factors as much as biological and genetic. So the best approach of the borderline personality disorder would be a multidisciplinary bio-psycho-social one. Through a clinical case, we illustrate this disorder and its treatment in outpatient clinic. [less ▲]

The effect of evaporative drying on the pore size of two series of hybrid silica gels is investigated by combining beam bending on the gels and mercury porosimetry on the aerogels and xerogels with transmission electron microscopy on the xerogels. It is shown that the shrinkage of the pores during drying is different in the two series: in one series the pores shrink proportionally to their volume, in the other the pores collapse until they all reach the same size. The experimental data enable us to discuss the relation between these two different behaviours and the different morphology of the two series of gels. [less ▲]

From a hybrid systems point of view, we provide a modeling framework and a trajectory tracking control design methodology for juggling systems. We present the main ideas and concepts in a one degree-of-freedom juggler, which consists of a ball bouncing on an actuated robot. We design a hybrid control strategy that, with only information of the ball’s state at impacts, controls the ball to track a reference rhythmic pattern with arbitrary precision. We extend this hybrid control strategy to the case of juggling multiple balls with different rhythmic patterns. Simulation results for juggling of one and three balls with a single actuated robot are presented. [less ▲]

The Zapara Indians in the Upper Amazon are on the verge of disappearing from the linguistic map. This is a fact. And yet, their emergence within the political landscape in Ecuador (but not yet in Peru), has provided them with a greater international visibility as an indigenous group. Most unusually, the accounts of dreams become one of the key elements of new forms of identity practices and identification processes – as those narrated here by two Zapara political leaders will attest. In search of their material and immaterial heritage, these leaders make use of the realm of dreams, using occurred dreams to orient their choices in the reconstruction of a collective memory. The dream, as a tool for engaging in a regredient process or in the return into the past, provides the historical elements that the Indians will then re-inject into their present in order to construct new “traditions”. In this dissertation, I will be describing the mechanisms, the learning of, and the local theories concerning the experience of dreams. In order to be understood, the dream must first circulate, and must have an issuer as a point of departure. Dreaming is also the means for a privileged relationship between human and non- human beings. Throughout this thesis, various systems of memory will be examined based upon empirical data revealing of the dreamt experience, but also of daily life, such as new teaching methods, or the creation of artefacts, produced both by ancestors or contemporaries. These accounts will help us to understand this new process of “Zaparaisation”, which depends as much on a process of ethno-archiving than on ethno-museography, and which awakens the immaterial.
